Custom Field (CRM)
A custom field is a data field a team adds to a CRM record — beyond the default fields like name and email — to track information specific to their own business or sales process.

What a custom field is
A custom field is a data field added to a CRM record type — contact, company, deal, or activity — that isn't part of the platform's default schema. Default fields cover the basics every business needs: name, email, phone, deal value, stage. Custom fields cover what's specific to one business: a real estate agency might add "listing address" and "commission split," while a recruiting agency adds "placement fee" and "candidate availability date."
Custom fields typically come in a handful of types — text, number, date, dropdown, multi-select, checkbox, currency — and the type constrains what can be entered. A dropdown field with fixed options ("New / Warm / Hot") keeps data consistent across a team; a free-text field doesn't, since two reps might type "hot lead" and "Hot Lead" as different values.
Where custom fields live
Custom fields attach to a specific record type (contact, deal, company) and appear alongside default fields on that record's detail view, in list/table views as sortable columns, and in filters and reports. Most CRMs let an admin add, reorder, or retire custom fields without needing a developer or a schema migration.
Example
A property management company adds a custom dropdown field called "Lease Renewal Status" to every unit's contact record, with options "Not Started," "Sent," "Signed," "Declined." The team filters the pipeline by that field each month to see exactly how many renewals still need follow-up.
Why custom fields matter
A CRM with only default fields forces a business to either shoehorn its own data into the wrong field (dropping a property address into a "notes" box) or track that data outside the CRM entirely, in a spreadsheet that quickly falls out of sync. Custom fields close that gap: they let the CRM's data model match how the business actually operates, which is what makes filtering, reporting, and automation possible on that data.
Automation and reporting downstream depend directly on custom fields being clean and consistent. A workflow that triggers a task when "Lease Renewal Status" changes to "Sent," or a report that breaks down pipeline value by "referral source," only works because that data lives in a structured field rather than free text. This is also why field sprawl is a real cost: every custom field a team adds is one more thing reps have to fill in correctly, and one more column a report has to account for. Reviewing custom fields periodically — retiring unused ones, converting free-text fields to dropdowns where the values have settled into a fixed set — keeps the data usable as the team and process grow.
